Some of those things are at home in Phobos.

Maybe there are ways to improve this ucent mul (avoiding magic 
constants, using foreach, using size_t, maybe with asm too and 
__ctfe):

         else static if (op == "*")
         {
             uint[4] a = toParts();
             uint[4] b = y.toParts();

             this = 0;
             for(size_t i = 0; i < 4; ++i)
                 for(size_t j = 0; j < 4 - i; ++j)
                     this += self(cast(ulong)(a[i]) * b[j]) << (32 
* (i + j));
         }
